I believe Olefin mentioned the 120mm AGS with hybrid drive back in one of his earlier posts. He used to work for United Defense on the AGS if I recall? There was another dude who wrote his Master's thesis on the AGS, I don't remember his name, but maybe he will chime in.
I thought the 120mm AGS with hybrid drive was a technology demonstrator. But I like the idea and would go with it in game if I could. Just waiting for Paul Mulcahy to whip up some stats.
